Gearing Suggestions? E-Revo Brushless Edition

I have an E-Revo Brushless Edition on pre-order, and it comes stock with the Castle MMM 2200kv combo. The stock gearing direct from Traxxas is 65/18. I am looking to order a couple other variations for the spur and pinion just to have on in hand....just in case. Let's say two of each. Please understand, I am not an "RC Newb", just a "Brushless Newb". Any suggestions? Thanks! And this isn't a "What am best gears?" thread either as Neil might refer to it as!

Screw you hippy!

I would say a 20 and 24tooth pinion would be good, along with a 62 and 68 tooth spur; that should be ideal to give you a broad range of adjustment for anything around the 30-50mph region, on 4-6s lipo (I think the BL Erevo comes with some optional gears as standard, not sure which ones exactly though).

Plenty of those hippies you are referring to here in Oregon!

Cool, thanks Neil! Just funning with ya! Yeah, I think it comes with some extra gears, but I am not sure either what is included. I will be running 4s for the most part, as I think it will do what I want it to quite well.
